C-GLYCOSYLFLAVONES FROM ZEA MAYS THAT INHIBIT INSECT DEVELOPMENT

Article abstract of DOI:10.1016/S0031-9422(00)81977-9

A new C-glycosylflavone isolated from corn silk inhibits the growth and development of the corn earworm, Heliothis zea.This new compound was shown to be a 2''-O-α-L-rhamnosyl-6-C-(6-deoxy-xylo-hexos-4-ulosyl)luteolin.Also found co-occurring in corn silk were minor amounts of the corresponding 6-C-glycosylated analogs of chrysoeriol and apigenin.Key Word Index - Zea Mays; Gramineae; maize; flavone C-glycosides; Heliothis zea; corn earworm; larval growth inhibitors; host plant resistance; keto sugars.
